I have this lovely 8 mini dome / semi sphere silicone bakeware (Tefal) which is great for making round cakes (used it to make mini angry birds) - I can't find it anymore bought it a few years ago however found something similar on internet

once cooled I cut the dome so they were level, scooped out a little bit and added the butter icing ....

I joined them together using "cake pop" mix I made using the off cut cake & butter icing

I then covered them in chocolate flavoured fondant .... very tricky

I did "cheat" and had to add some fondant on the bottom and blend the joins

To make the "sauce" I used a round cookie cutter and hand shaped with a sharp knife

added some sparkle the "sauce"

Now making the Holly Berries & Leaves

I bought some special Beau Flowerpaste which happened to be "holly green". I use a holly leaf cutter but you could easily just cut the shape with a template & knife.

The holy berries was just some red fondant icing which I added some "Christmas Red" colouring to do make them more red. I added them to the leaves and used a leftover apple packaging from Sainsburys to shape the leaves in to the dome shape..... (I made these first and left them to dry while I made the cakes)

Once I'd made the cakes I added the holly to the top using a bit of icing & water mix .....

To make them nice for the fete, I placed them on 4" silver bases and bagged & tagged
